Help, orange algae??

[dlynch8802]

Hey guys. So I've searched and searched, and read and read, and could not find much on an persistent issue I've been having. For the past months I have had an issue with Po4 stabilizing at .25. I added a reactor and got it down to .1 but since then I have had a rampant orange algae (yes orange, I do t know what it is) outbreak that is starting to affect my corals. Some pictures are below

Those are just a few, and the last showing the destruction of my pink lemonade frag. It's on everything, noticeably on my power head, pumps, and various sponges (used as a filtration) as well as all rock, but not on the sand bed. There's no bubbles in it and it's not stringy like cyano so I ruled that out. My thought was dinos, but no sure.

My parameters are as follows:

No3: 2.5 - 5
Po4 .03 - .1
Alk: 7.3
Ca: 405
Mag: 1230

All tested with salifert.
I know my mag and ca are low and am bringing them back up slowly (I was away for a week and didn't want my gf to dose anything while I was gone). I also dose 2 ml of NoPox daily. I'm running no sump, but have a reef octopus classic 1000 hob skimmer and a hob refugium with chemi pure blue and various types of chaeto in it.

Anyone have any ideas? I'm bummed because it's starting to kill all my sps

Also, I notice it looks brown in the pictures, but it's fluorescent orange

I'm also bumping up my mag to 1500 to see how it resoonds

How many gallons is your tank? Try upping the NOPX dosage?

I have a 29 gallon standard tank. Is dosing more than that ok?

Here are some more pics with just whites in

It just looks like Diatoms to me.

Thank you guys, I do think it's diatoms now, but I'm still baffled that this hasn't run its course. It's been almost three months, and the worst of it had been a a couple weeks. It looks like I need to decrease my silicates, but I'm not sure where they are coming from

Maybe some of the info in this video can help you out
